Answer 1
Answer:

Answer:

Step-by-step explanation:

Ray hired sun and peter to help him move.

Let h represent the number of hours that each of them worked.

Let y represent Ray's total cost for hiring Sun and Peter for h hours.

Sun charged a $20 flat fee and $30 per hour. The total amount that Sun charges would be

20 + 30h

Peter charged $25 per hour. The total amount that Peter charges would be

25h

An expression for Ray's total cost if Sun and Peter each work h hours would be

y = 20 + 30h + 25h

y = 20 + 55h
Answer 2
Answer:

Answer:

[20+(30+25)]h or (20+55)h

Step-by-step explanation:

20 will not be changed.

Total cost per hour is 55

add $20

Hope this helps

If m<1=140, what is m<3

Answers

m < 1 = 140
m < 2 = 40

m < 2 + 90 + m < 3 = 180..(total of angles in a triangle are 180)
40 + 90 + <3 = 180
130 + <3 = 180
m < 3 = 180 - 130
m < 3 = 50

I assure you the answer is 50!

\textsf{The correct answer is the third one (below the one that you selected).}

Explanation:

\sf\n\textsf{In first option, when x = 2, y = 1 and -1. There are two y-values for one x-value}\n\textsf{so this is not a function.}

\textsf{In second option, there are infinite y-values for x = 3. So this is also not a}\n\textsf{function.}

\sf\n\textsf{In the third option, there are unique y-values for every values of x. Hence this is}\n\textsf{a function. Actually, the function shown here is a cubic function }y=x^3.

\textsf{In the last option, x = 1, y = 2, -2. Here also exists two y-values for a single x}\n\textsf{value. So this is also not a function.}

An airplane flies six hundred miles to the south; then, after landing and refueling, it flies due north for three hundred miles. What is the airplane's displacement? (Remember, displacement is a vector, so direction needs to be indicated in your answer).

Answers


Displacement =

in the direction of
     (direction from the start-point to the end-point).

For the entire story, the displacement is

                         300 miles south .
If it's going 600 miles S, and 300 miles N, the displacement is 300 miles S

x2 - 2x + = 4(x2-2x +1)-3

Answers

Answer:

-3x² +6x -1 = 0

Step-by-step explanation:

x2 - 2x + = 4(x2-2x +1)-3

x² - 2x = 4x²-8x +4 - 3

x²-4x²-2x+8x = 4-3

-3x² +6x = 1

-3x² +6x -1 = 0

Hi Mark

3x+y=4

2x+y=5

Solve 3x+y=4 for y

Add -3x to both sides

3x+y-3x=4-3x

y=-3x+4

Substitute -3x+4 for y in 2x+y=5

2x+y=5

2x-3x+4=5

Simplify both sides of the equation

-x+4=5

Add -4 to both sides

-x+4-4=5-4

-x=1

Divide both sides by -1

-x/-1= 1/-1

x=-1

Substitute -1 for x in y=-3x+4

y=-3x+4

y=(-3)(-1)+4

Simplify both sides of the equation

y=7

Answer: (-1,7)
